FIELD: metallurgy.
SUBSTANCE: invention can be used for opening of outlet channel of bucket with shutter gate. Metal boom (1) is placed in channel of bucket nozzle-bucket (2) with stop of upper end into working surface of fixed fire-resistant plate (6) of gate shutter. Lower end is forked and pressed by lower resilient flexible element. Resilient element is made in form of two detachable leaf springs (7) cantilevered on metal shell (8) of the nozzle-collector, and string (9). Each of springs with free end is connected with string with tension, with possibility of its ejection at moment of complete easing of tension.
EFFECT: enabling increase in the catapult structure most part use ratio increase due to the catapult main elements removal from the metal melt jet impact area.
